To all whom it may concern: I

Be it known that I, DOMINA QUINTAL, a British subject, residing at Letang Street, in the city of lvlontreal, in the Province of Quebec, in the Dominion of Canada, have invented certain new and useful improvements in. Railway Switches; and I do hereby declare that the following is a true, clear, and exact description of the same;

The present invention relates to. improvements in a railway switch, and. is fully described in the following description and illustrated in the accompanying drawings, in which t Figure l is a plan view of aswitch according to the invention, with the switch members alining with the main line rails.

Figure 2 is a side elevation of Figure 1.

figure 3 is plan view with the switch members alining' 'ith the switch line rails Figure 4: is a cross section on line l-l of Figure 1.

Figure 5 is a bottom plan the switch members. v Figure (5 is a side elevation of the cams operating the switch members, mounted on their shaft.

Figure 7 is an enlarged plan viewof the quadrant operating the switch shaft.

Figure 8 is an end view of Figure 7. Figure 9 is an enlarged sectional view through a portion ot the switch operating mechanism casing.

Figure 10 is an enlarged plan view of the locking element adapted to lock the switch.

like numerals of reference indicate corresponding parts in each figure;

Referring to the drawings, 1 indicates the main line rails, and 2 the switch line rails. Intermediate of each of said main line rails and said switch line rails there is formed a suitable longitudinal recess 3, and in the bottom wall or face or" each of said recesses is formed a hole 4. The switch members 5 are suitably mounted in said recesses 3, and each is provided with a pivot pin 6 adapted to engage the hole 4: in the corresponding recess 3, said switch members being provided with the usual tread surfaces 7, and longitudinal and parallel flanges 8, said tread surfaces 7 being adapted to come in alignment with the treads of either the main or the View of one of vided at the opposite end of the pivoting point with an enlarged flat portion 5 eachin said reces ref ndicator 28. The edire or rim or quadrant 21 is provided adjacent the teeth 22 with preferably two holes 29, said holes being at an equal distance from the pivoting point of said quadrant and adapted to be engaged by the of said flat portions 5 havinga curved outer end 5 adapted-to tit in thecorrespdndingly curved end 01 the main and switch rails 1 and 2. I The switch members are firmly held in said recesses 3 by means of the blocks 9 which are ri, dly secured to the mainrails by the bolts it). afit their opposite ends the said members 5 are slidably held in position s by means or" the plates 11 which are each secured respectively to the main and switch rails l and 2 by the bolts '12. On the under side of each of said members 5 are locatedyin the flat portions 5 the cam recesses 13 and 1%, said recesses being adapted to receive respectively the cams 15 and 16. Each cam 15 or 16 is so'dis'posed in relaently, to-swing; saidswitch member 5 from.

one side to the other, said movement from one side to the other depending on ,therotation of the shatt controlling the cams. The said cams15 and. 1.6 are rigidly mounted in pairs on the camv shaft 17, said shaft extending. outwardly on one side thereof and being provided on its outwardly extending, portion with a pinion 18.

Ahoy X said pinionlS is provided a casing l9 iu' whi-ihv there is suitably journalled a horizontal stub shaft On said shaft 20 is mounted a quadrant 21 which meshes with .thepinionIS, said quadrantbeing provided its upper edge with the bevelled teeth 22 ch. mesh with the small quadrant 23, and vertical 7 shaitt suitably journalled in L e b ticket 25 atone end. At its lower end shaft 24; carries said quadrant 23, and is suit-- ablyiournalled in the bracket 26, said shaft erably carrying the-signal light 27 and l wl l i 3O projecting downwardly tromthe sriuember 31. Said locking member is ided with the vertical slot 32. and is wiblyheld in position between the outer wall of the casing 19 and the partition and normally pressed downwardly by means of the spiral'spring 34 which abuts. against the top of the casing- 19 at one end and rests against the upper end of said member 31.

The casinglll is preferably provided with a keyhole 35 through which may be inserted the key 36 said key passing through the slot 32 and being adapted to lift said mer ber 31 out of engagement with the quadrant 21 by means of the lug 37 provided thereon.

In the operation of the invention, the operating lever 38 which is mounted on the shaft 20 is thrown from left to right or vice versa, and by so doing actuates the shaft 17 which in turn operates the cams 15 or 16 and moves the switch members 5 from the main line rail to the switch rail or from the switch rail to the main line rail. Simultaneously on operating the lever 38, the shaft 20 actuating the quadrant 21 swings toe quadrant 23 from right to left thus turning the shaft 24 and indicating whether the switch is open or closed. Prior to the operation of the lever 38 the key 06 must be turned so as to disengage the locking member 81 as otherwise the quadrant 21 will be prevented from movement, as well as the lever It will thus be readily seen that without the key to unlock the quadrant 21 it is absolutely impossible to operate the switch.

The invention above described and disclosed in the accompanying drawings is shown in one of its pr erred forms but as it is only in its experimental stage it may naturally be altered from its form later on without departing from the scope oi? the fol lowing claims, and spirit of the invention.

What I claim as my invention is l. A railway switch comprising, in combination with the main line rails and intersecting switch line rails a pivotally mount 7 switch member having a cam recess; a sham; means to operate said shaft; and means on said shaft adapted to engage said cam recess, substantially as described.

' 2. A railway switch comprising in. cornbination with the main line rails and inter secting switch line rails a pivotally mounted switch member provided with two cam recesses operating in opposite directions; :1v shaft; means to operate said shaft; and means on said shaft adapted to engage said cam recesses substantially as described.

3. A railway switch comprising in comeas es bination with the main line rails and intersecting switch line rails a 1 )iv\'itall mounted switch member having cam reces es; a shaft; means to operate said she cams mounted on said shaft adapted to engage each of said cam recesses; and means to lock said shaft substantially as described.

4-. A railway switch comprisin in combination with the main line rails and intersecting switch line rails pivotally mounted switch member provided "with cam recesses; a shaft; means to operate said shaft; cams mounted on said shait adapted to engage each of said can. recesses; a pinion mounted on said shaft; a stub shaft suitably journalled adjacent aid shaft; a quadrant adapted to engage said pinion; means to opv crate said stub shaft; and means to lock said between the operating shaft and the switch shaft for transmitting movement from the former to the latter; and a locking device ongageable with one of the gears included. in said connection to prevent rotatio 6. In a railway switch, in combin tion with the main and switch tracks a pair of switch members; a switch shaft havi: means cooperative with the switch members to shift the same from one position to the other; an operatinn' shaft; gears connec the operating shaft and the switch shaft transmitting movemei'it from the former to the latter one of s id gears having;- e. re cessed rim; and a h ig device releasably engageable with said rim to prevent rotation of said gear.
